摘要:
A bifunctional compound containing an amino group and diaminedithiol ligand and a manufacturing method thereof are revealed, the bifunctional compound includes at least one amino group and a diaminedithiol (N2S2) ligand. The amino groups is for reacting with compounds containing carboxylic acids or halogens while the N2S2 ligand binds with technetium or rhenium so as to form an anion complex. The thiol group in the N2S2 ligand is protected by a protecting group for prevention of oxidation and easy storage. This protecting group is released easily during complex reactions. Due to the bifunctional property, the compound is applied to preparation of radiopharmaceuticals such as imaging agents and targeted agents.

摘要:
A heat sink used in an interface card includes a supporting base, a first heat-dissipating body and a second heat-dissipating body. The supporting base has a side. The first heat-dissipating body is mounted on the supporting base. The first heat-dissipating body is constituted of a plurality of overlapping heat-dissipating pieces. The heat-dissipating pieces are arranged obliquely with respect to the side. The second heat-dissipating body overlaps on the first heat-dissipating body. The second heat-dissipating body comprises a plurality of heat-dissipating pieces. Via the above arrangement, the heat-dissipating efficiency of the interface card can be increased and the lifetime thereof can be extended.

A motor structure with a built-in lens includes a motor (30), and a lens unit (50) received in the motor and driven by the motor to telescopically move along an axial thereof. An internal thread (344) is formed on an inner surface of the motor. The lens unit includes an upper portion (51) and a lower portion (54). An external thread (544) is formed on an outer surface of the lower portion of the lens unit to threadedly engage with the internal thread of the motor. A dust cover (70) is arranged on the upper portion of the lens unit and defines an opening (71) for the upper portion of the lens unit to move therethrough. The lower portion of the lens unit is limited in the cover so that the external thread is prevented from being exposed to the environment during movement of the lens unit.

A ceramic capacitor assembly has a ceramic capacitor and a cushion. The ceramic capacitor has a body, two terminals formed respectively on the body and two legs connecting to and protruding respectively from the terminals. The cushion is a resilient material and has an upper surface corresponding to and mounted adjacent to the ceramic capacitor, a lower surface, an outer edge and two fastening detents. The detents correspond to the legs and are provided for legs to fasten to the cushion. The ceramic capacitor and the cushion are easily assembled and reduce cost and complexity of manufacture.

A backlight module (2) includes a light source (21) and a light guide plate (23). The light source includes a lamp (231) and two electrode cases (233), the two electrode cases engage with opposite ends of the lamp. The light guide plate includes a light output surface (212), a bottom surface (213), two adjacent light incident surfaces (211), two side surfaces (214), and two holding devices (215). The two holding devices are respectively provided at diagonally opposite corners of the light guide plate, where the light incident surfaces are respectively adjacent the side surfaces, and the holding devices are for retaining electrode cases. The light source is disposed adjacent to the light incident surfaces. The lamp are not liable to shock, so the lamp can not be damaged. Further, the backlight module eliminates the need for rubber rings. Thereby reducing the cost of the backlight module.

A gravity sensor has a photo interrupter and a gravity wheel. The photo interrupter has a housing, a cavity in the housing, a light emitter on one side of the housing and a light detector on the other side of the housing. The gravity wheel points in a direction of gravity and has a pivot at center thereof and pivotally arranged on the housing, a plumb at one edge of the gravity wheel and a plurality of through holes annularly arranged in the gravity wheel. The gravity wheel has a portion present in the cavity. An inclined angle of a test object is determined by calculating relative movement between the photo interrupter and the gravity wheel.
